chore: sync public mirror from internal

[evalops-mirror]

Summary

• sync the sanitized public tree from dx-corp/mono
• keep dx-corp/code as a generated public mirror of the private source of truth
• preserve public-owned CI and trusted-publishing workflows from the public checkout
• internal source SHA: 03ccf8fea13e310f4d2fd6dd92736749692f3344
• last generated public sync base: 9c490dd81e4c467066295a5f88d01d2f05366a08
• previewed public-tree drift: 9 file(s) to copy/update and 0 stale file(s) to delete
• public-only commits since last generated sync: 0
• to pause generated syncs while hand-editing this branch, apply the sync-hold label to this PR; the sync workflow skips every push while it is set

Public-only commits since last generated sync

• none detected since last generated sync

Validation

• generated by the sync-public-release-mirror workflow in public-tree mode

Test Plan

• generated by the maestro-sync-public-release-mirror workflow in public-tree mode
• public-source-provenance require-internal-pr confirms internal source PR lineage
• generated mirror PRs use the slim public CI path (fmt/clippy/smoke + provenance); full cargo test/evals already ran on internal main for this SHA
• bot review threads on generated mirror PRs are advisory and do not block the next sync update

Staged Rollout

• Staging is unnecessary for this generated mirror PR: it does not independently promote user-visible behavior. It mirrors already-reviewed internal source from dx-corp/mono@03ccf8fea13e310f4d2fd6dd92736749692f3344, including existing hidden/evaluation surfaces, and keeps public package parity behind the established public-source-provenance gate.

Stop gallery playback before activating the studio

When the user clicks Play and then New menu scene, the timer created by the gallery play handler continues calling paint() because activate() only hides the gallery controls. Those callbacks repeatedly overwrite the authored capture, transcript, status, and source link while the inspector remains active, making the studio preview unreliable until the hidden playback is stopped; call stop() when entering the studio.
